Application filed April 22, 1925. Serial No. 24,928.

This invention relates to universal joints,

and mor-e particularly to joints of thevchar-V acter wherein the trunnions are mounted in and connected by al member inthe shape of a ring having a chamber or chambers for It is the general purpose and object of the invention to p rovide a construction of universal joint of this character wherein the trunnions may be efficiently lubricated; also to provide a joint which is practically leak-proof, which is cheap of manufacture, and which is easily assembled and disassembled.

Further and ymore limited objects of the invention willappear hereinafterV and will be realized in and through the construction and arrangement of parts shown in the drawings, wherein Fig. 1 represents a sectional elevation of a universal joint embodying theinvention; Fig. '2 a similar view,

taken at right angles to F ig. 1; Fig.3 a side Y elevation and Fig.v 4 an end velevation of one of the bearing blocks; and Fig. 5 an elevation of one of the packing rings einployed with said bearingblocks.

Describing the various parts by reference` characters, 1 and 2 denote hubs by means of i which the joint is connected to shaft sections v sections each comprising an vouter cylindrical (not shown), the hub 2 being shown as adapted for a splined connection with its shaft section, the outer end of the hub bore being closed by a plate 3. The hubs are provided each with a yoke, the arms 4 of each yoke having a cross pin v5 mounted therein, the outer ends 6 of each cross pin constituting trunnions. Each cross pin shown as provided witha centralrecess 5a of slightly greater depth than theiadius of such pin, each recess being about Q10o in angular extent to accommodate the rocking movements ofthe pins. The trunnions are adapted to be mounted in bearing blocks carried by and supported within a connecting member inthe form of a ring, the ring being indicated generally at A. The ring is preferably made from two symmetrical wall 7, an annular side wall 8, and an inner cylindrical wall 9,'the inner wall being segmental or discontinuous. The ring sections are made of malleable castings and the lmeeting edges 10 and 11 are machined to secure f l a close t therebetween. Each of the meeting edges 10 and 11 is provided with a channeled annular recess 12 which, when the sections are assembled, provides an annular groove located radially'outwardly from theV seats B, which groove receives a packingv gasket 13.

Each ring section is provided, within the side wall 8 thereof, with a seat recess extending transversely thereof through the edge 10 or 11 thereof, said recesses forming, when the sections are assembled, seats B for the bearing blocks, said seats each being in the shape of a segment of a cylinder intersecting the inner wall of the ring and having a circumferential extent in excess of 180,fwhereby the seats permit their respective blocks to 'y rock therein while preventing radial inward movement of the said blocks.

It' willbe noted vthat thev space between the outer wall and the segmental inner wall f of the ring is divided into a pluralityk of chambers C, said chambers being separated from each other by means of the side. walls `of the lubricant by centrifugal action', by

inerge at their inner ends with the openings 14. For the'puiposeof supplying the chambers with lubricant, one such`clia1nber 'ico cylindrical radial bore 17k therethrough. The ends of the blocks D are reduced, as shown atD, providing around each such eXten-Y rthe ends Vof eachI trunnion and between the same and the cooperating part or' the seat l),

the ports 15 and 211connectingfadjacent chambers C. A The ports 15 and 21 communi.- cate with avcentralgaxial .chamber 2Q, eXfv Y tending linwardly from ,the outer end of each trunnion, from which chamber aport.V

,23 extends to the seat provided-,foreach lthereof compressing the packing; ring 13 and k.forcingthewashers 7.119 against their seats and about the `extensions D.V lThe ring trunnioi'i within its bearing block,y the ports' 23 extending at right angles to the plane of rotation of the ring.`

vWith 'the parts constructed and arranged Vas described, the hubs, with.their trunnions.V f and the bearing"blocks thereon, arerapplied tothe rino' b securing the two rinosections i E: Y D b together bymeans vof thebolts `24, seeing' that the washers 19 are in place and thatthe VpackingV ring 13 is seated on one of the re.

Ycesses 12. V ByV setting .uptlie nuts -on the said bolts, the ring sections will Ybe secured together rinzsuch manner as to forma tight,n

joint between the ineetingaedges 10 fandf 11 13 and washersV 19 vare locatedat the points where greatest pressure of lubricant is eX- v erted,-due to .the centrifugal act-ion, and` 'etfectuallv seal` the "oints between the rino` .l i .i i :5

Y sections andv betweenithe blocks and thev ring at such places;v and the whole construction!` .enables the-parts to be Vassembled and Vdis-y Y assembled quicklyand conveniently and reduces to a minimum the liability ofleakage.;

Cil

'Furthermore.v the construction-of the bear-A ing blocks and the mannerof mounting the Y sameenables them to align themselves properly with respect to the crosspins "and the; trunnions dur-mg the assembling operation and during the operationfof the joint.

Theshape oftheseats Band blocksD enables thebloclrs-to loe-retained in the seatsv against radial inwardY movement, but" with theca'pability of rocking in said-seatsthere'- byto facilitatev the -assembling operation.

Bv reason oft-heY construction illustrated described herein,'l am enabled to pro-n vide: Joint ofzthe Ycharacter referred to hereinbet'ore ywhich issim'p'e and economical- Y offlprodiiction,which 'will Vreducefto a vminimum the machining operations, and which will also reduce to a minimum the liability of lubricant to leak therefrom.
